I think I know what it is but I'm more interested in how you did the shot Rich. I'm not going to guess because If I'm right I'm not sure I can come up with another game. Maybe you can explain how you shot it after someone gets it.

I don't believe it is my reflection. The darker area in the upper right of the image is the top of the funnel of the vortex created by the water rushing down the drain in the lower left of the image. Kind of like a tornado, but viewed from above. The bright spot in the top of the funnel is, I believe, a reflection of the sky above.
